Grammys 2013: The Biggest and Best Moments From the Show

The 2013 Grammy Awards brought show-stopping theatrics and vocals from Rihanna, fun., Kelly Clarkson, Carrie Underwood, and more -- but there were plenty of highlights between performances, too. Relive the biggest, buzziest moments from the 2013 Grammys below.

Sounds like someone's got a message for Harry Styles! Taylor Swift opened up the 2013 Grammy Awards in L.A. with a white-and-red circus-themed performance of her hit "We Are Never Ever Getting Back Together" -- and a dig at her British boy-bander ex.

Time heals all wounds, apparently. Four years after Chris Brown's assault of then-girlfriend Rihanna before the 2009 Grammys, the on-again couple returned to the awards show together. After walking the red carpet separately, the singers reunited inside Staples Center, where they happily cuddled in the audience.

Back and better than ever! Justin Timberlake did not disappoint when he made his much-anticipated return to the Grammys stage. Joined by pal Jay-Z, the singer delivered a retro-tinged performance of his hit "Suit & Tie" and a new song, "Pusher Love Girl."

"Blown Away" is right! Carrie Underwood's Grammys performance -- and technicolor gown -- wowed the crowd at L.A.'s Staples Center, but people were talking about her even before she took the stage. The reason? Her out-of-control bling, worth some $31 million.
